ISL59483

Dual, 500MHz Triple, Multiplexing

Amplifiers

The ISL59483 contains a gain of 1 triple 4:1 MUX amplifier

(MUX1), and a second gain of 2 triple 4:1 MUX amplifier

(MUX2). Each feature high slew rate and excellent

bandwidth for RGB video switching. They contain separate

binary coded, channel select logic inputs (S0, S1), and

separate logic inputs for High Impedance output (HIZ) and

power-down (EN) modes. The HIZ state presents a high

impedance at the output so that both RGB MUX outputs can

be wired together to form an 8:1 RGB MUX amplifier or they

can be used in R-R, G-G, and B-B pairs to form a 4:1

differential input/output MUX. Separate power-down mode

controls (EN1, EN2) are included to turn off unneeded

circuitry in power sensitive applications. With both EN pins

pulled high, the ISL59483 enters a standby power mode,

consuming just 36mW.

Features

• Separate gain of 1 and gain of 2, triple 4:1 multiplexers for

RGB

• Externally configurable for various video MUX circuits

including

- 8:1 RGB MUX with selectable gains of 1 or 2

- Two separate 4:1 RGB MUX with gains of 1 and 2

• High impedance outputs (HIZ)

• Power-down mode (EN)

• ±5V operation

• ±870V/µs slew rate (G = 1), ±1600V/µs slew rate (G = 2)

• 500MHz bandwidth

• Supply current 16mA/CH

• Pb-free plus anneal (RoHS compliant)

Applications

• HDTV/DTV analog inputs

• Video projectors

• Computer monitors

• Set-top boxes

• Security video

• Broadcast video equipment

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
